Do I have to replace the fuse of an actuator if the damper has been closed as a result of a temperature higher than 72° in the ventilation duct?
If the temperature in the air duct exceeds 72°C, the (thermo-electric) fuse interrupts the supply voltage and the blade closes. The fuse needs to be replaced, but the motor itself will continue to function normally. The fuse can be easily replaced with a kit.
